Example:
RP/0/RP0/CPU0:router# show bgp update-group 0.0
Displays information about BGP update groups.
• The ip-address argument displays the update groups to
which that neighbor belongs.
• The process-id.index argument selects a particular
update group to display and is specified as follows:
process ID (dot) index. Process ID range is from 0 to
254. Index range is from 0 to 4294967295.
• The summary keyword displays summary information
for neighbors in a particular update group.
• If no argument is specified, this command displays
information for all update groups (for the specified
address family).
• The performance-statistics keyword displays
performance statistics for an update group.
